Abstract

Abstract: Numerous ingenious top‐down methods have opened a new door to the extensive research of 2D crystals. In this paper, a novel "differential‐temperature exfoliation technology" is proposed to synthesize 2D few‐layer MoS2 . Several characterizations are conducted for discussion. The spectroscopic, optical, and purification capacity of the as‐exfoliated layered structures is further studied systematically. This research provides insights into the novel top‐down production and the related potential for environmental protection of few‐layer MoS2 . Abstract : Driven by differential temperature, this study innovatively explores a green strategy of differential‐temperature exfoliation technology (DTET) for exfoliating 2D MoS2 nanoflakes. In this work, it is found that the differential‐temperature has the potential to be applied to the environmentally friendly preparation of few‐layer crystals. Furthermore, the excellent purification performance toward methylene blue of the DTET‐prepared crystals is detected.
